Abstract
Samples with nominal starting compositions (Tl1-xRex)Sr2CaCu2O7-δ (x = 0.05-0.30) were prepared by the solid state reaction method. Superconducting fluctuations and excess conductivity analysis was carried out using the Aslamazov-Larkin (AL) theory to determine the dimension of fluctuation induced conductivity λ. The Lawrence-Donaich (LD) theory was used to calculate the coherence length ξc(0), Josephson coupling J, and anisotropy γ = (ξab(0)/ξc(0)). XRD patterns indicated that the samples were dominantly Tl-1212 phase. Substitution of Re in place of Tl in (Tl1-xRex)Sr2CaCu2O7-δ showed Tc onset between 70 K (x = 0.05) and 82 K (x = 0.25). Excess conductivity analyses showed that Re substitution induced 2D-to-3D conductivity transition with the highest transition temperature, T2D-3D observed at x = 0.25. The calculations based on Lawrence-Doniach model showed the shortest coherence length, ξc(0) and highest anisotropy(γ =13.42) for the x = 0.25 sample.
